Show, further include light sensing unit 107 close to sensing device further, it can be electrically connected at control unit 105.Light sensing unit
107 can sense the luminous intensity in environment, and the ambient light intensity signal input control unit 105 that will represent luminous intensity.
Control unit 105 can be defeated according to the capacitance and light sensing unit 107 of the input of measuring unit 104 simultaneously
The environmental light intensity signal entered judges whether that lighting unit 106 is controlled to light to irradiate the button 101.For example, it can obtain in advance
The luminous intensity under multiple and different environment is taken to be analyzed, including different time sections, under the luminous intensity of different zones, human eye is for pressing
The visuality of key is counted, and the luminous intensity in the range of human viewable is counted a visual range of light intensities, control unit
Whether 105 carry out the ambient light intensity signal got to be converted to ambient light intensity, judge the ambient light intensity described
In visual range of light intensities, if in the visual range of light intensities, even if the capacitance changes or the capacitance
Value is fallen within the preset range, and lighting unit 106 will not be controlled to light, if the ambient light intensity is not in the visible light
In strength range, and the capacitance changes or the capacitance is fallen within the preset range, then controls illumination single
Member 106 is lighted.By present embodiment, the device energy can be saved or extend service time of battery, daytime light it is preferable
Under environment, even if human body will not light lighting unit, realizing both can be preferable in light close to triggering sensing electrode
